[0028] Example 1
[0029] In the related art, in order to measure the environmental parameters inside the oven, multiple sensors are usually fixed at designated positions inside the oven. However, for continuous ovens, the material is placed on a loading cart, which is placed on a conveyor belt inside the oven. The material is transported to each oven section along the conveyor belt. During the transportation process, the material passes through different positions inside the oven, and its environmental parameters may be different. Monitoring the internal temperature of the oven through fixed sensors cannot track the changes in environmental parameters caused by changes in the material position in real time. In this regard, the embodiment of the present application provides a measuring device 100.
